Abstract

The utility model belongs to the cooking stove, and discloses a coal and firewood two-purpose energy-saving stove used in villages and towns. The coal and firewood two-purpose energy-saving stove is provide with two burning chambers, an adjustable fire grate and a secondary ventilation door which can provided sufficient air. The utility model has the advantages of saving energy, material saving, little pollution, small size, convenient operation, etc., and the utility model not only can use firewood, but also can use coal as fuel.

Description

High-efficiency energy-saving coal and firewood stove

The utility model belongs to drink thing stove, is useful for the energy-conservation stove of small towns coal and firewood two purpose.

Traditional cauldron brick kitchen range is used in present vast rural area, generally can only burn faggot, can not burn coal; And, use various coal stoves near many small towns in rural area, and often can only burn coal, can not burn faggot again.Because its design feature fuel combustion is insufficient, smoke contamination severity.

The purpose of this utility model is, sets up an adjustable fire grate and two combustion chambers, makes stove can use faggot can make coal again, and sufficient combustion, reduces and pollutes, and uses also very convenient.

The utility model is to realize like this, adopt two combustion chambers, first combustion chamber and adjustable type second combustion chamber, a fire grate guiding mechanism is installed in the stove hall, make that the stove hall is adjustable as required to be turned down greatly, a lower wind door is arranged below the stove hall, be provided with 360 ° of airintake wind-tunnels in the stove hall outside, upper wind door is arranged on the air channel, and stove hall material is an exotic material.

Further specify below in conjunction with accompanying drawing

Figure: be the utility model schematic diagram

See figure, (1) flue, (2) first combustion chambers, (3) second combustion chambers, (4) burner hearth, (5) 360 ° of airintake wind-tunnels, (6) fire grate guiding mechanism, (7) lower wind door, (8) upper wind door, (9) stove hall inner ring, (10) secondary air inlet hole.

Fire grate guiding mechanism (6) when needs port thorax, can be adjusted screw thread with the suitable stove hall bottom that is installed in of shape of microgroove, and fire grate is risen, and descends otherwise then adjust fire grate.

This stove in use, earlier put into faggot or coal on the fire grate of burner hearth (4) from top fire door, after putting enough fuel, by top igniting, fuel fully burns in first combustion chamber, in burning, lower wind door (7) and upper wind door (8) make fuel be able to sufficient burning can both for the enough air in first combustion chamber, however, it is abundant also to have part combustible unburned, they can enter and be looped around the further burning of second combustion chamber (3) on every side, first combustion chamber (2), and are so not only less from the flue dust that chimney (1) comes out, and can also improve the temperature of flame.

It is 1.5～2 millimeters thick steel plates that stove hall inner ring of the present utility model (9) can adopt material, or HT150 cast iron, or pottery etc., several secondary air inlet holes (10) are arranged on the stove hall inner ring (9).

The utility model has the advantages that:

1) strong adaptability can dryout bavin, wet bavin and irregular faggot, also can burn honeycomb briquette, coal briquette etc.

2) energy-saving effect is remarkable, sufficient combustion, and fuel saving economizes on coal 30% than 3～5 times of existing stove joint bavins.

3) easy to use, single step of releasing foot fuel.When drinking, need not add material, promptly convenient health again.Igniting also is conveniently to save trouble in the employing.

4) pollution is little.Because fuel can fully burn, and therefore, substantially smokelessly emerges.

5) simple in structure, volume is little.
